Understanding Vertical Units

You can identify a vertical unit (U) mark as a round hole along the edge of the side rails. Note
that it is smaller than the mounting holes used to secure equipment in a rack. The 40 U rack
additionally uses a square hole to indicate every fourth vertical unit. You should determine
the vertical mounting space within a rack enclosure for each device you wish to install. For
example, an AC distribution box can require 1 U or 2 U of mounting space, while a server
requires five vertical units (5 U), or 8.75 inches, of mounting space.
u
A vertical unit equals 1.75 inches and consists of three mounting holes.
u
The mounting hole diameter is 7.1 mm (industry standard).
u
Mounting holes are counted upward after locating the first mounting hole within the range
of vertical units required to install the equipment.
The following figure shows installing a tinnerman nut to mounting hole 3 of a vertical unit.
